Title: Cast resin molding and its production
Inventor: MAEDA TERUHIKO
IPC: B29L31/34
Filed: 1993-12-28
Abstract: PURPOSE:To provide a cast resin molding which is used even under the very dusty and high-humidity environment and is difficult to generate decomposition gas in the case of a fire or the like. CONSTITUTION:An inorganic filter 4 such as alumina and silica is incorporated into the resin layer 3 of a cast resin molding. In the case, the inorganic filler 4 existing on the surface part of the resin layer 3 is in an exposed state by thermally decomposing the resin layer 3 on the surface part in the atmosphere containing oxygen. Therefore, the content of the inorganic filler 4 on the surface part of the resin layer 3 is higher than the inside. An electroconductive path is difficult to be formed even when cast resin is decomposed by leakage current. Therefor, a cast resin molding is used even under the very dusty and high- humidity environment because there is no danger of causing flashover.
